HD74LVC125A

HD74LVC125A Quad. Bus Buffer Gates with 3-state Outputs ADE-205-108B(Z) 3rd Edition December 1996 Description The HD74LVC125A has four bus buffer gates in a 14 pin package. The device require the three state control input C to be taken high to put the output into the high impedance condition, whereas the device requires the control input to be low to put the output into high impedance. Low voltage and high speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation. Features VCC = 2.0 V to 5.5 V All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VOUT (Max.) = 5.5 V (@VCC = 0 V or output off state) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±24 mA (@VCC = 3.0 V to 5.5 V) Function Table Inputs C H L L H: L: X: Z: High level Low level Immaterial High impedance A X L H Outputs Y Z L H HD74LVC125A Pin Arrangement 1C 1 1A 2 1Y 3 2C 4 2A 5 2Y 6 GND 7 14 VCC 13 4C 12 4A 11 4Y 10 3C 9 3A 8 3Y (Top view) Absolute Maximum Ratings Item Supply voltage Input diode current Input voltage Output diode current Symbol VCC I IK VI I OK Ratings –0.5 to 6.0 –50 –0.5 to 6.0 –50 50 Output voltage VO –0.5 to VCC +0.5 –0.5 to 6.0 Output current VCC, GND current / pin Storage temperature IO I CC or IGND Tstg ±50 100 –65 to +150 Unit V mA V mA mA V V mA mA °C VO = –0.5 V VO...
